River Sand is a natural sand that is made from weathering or erosion processes, unlike other sands that are made from crushing rock. River Sand can vary in gradation but is typically coarse sand. It can be used in all types of landscaping and construction projects including concrete sand, drainage areas, arena footing and soil amendments. It is made from the same material of the local rock it eroded from, so usually it is mainly silica sand from quartz. Our River Sand is sub-angular in shape, but other sources can be rounded.
